Anthropic recently announced that all new Claude models will embed an invisible signal into their text output. The goal is to help identify AI-generated content and meet new transparency requirements under the European Union's AI Act.
But if you're picturing an invisible digital stamp that permanently proves the words were written by AI, that's not exactly how it works. Instead, Claude subtly changes the statistical patterns in its writing. The text still reads naturally to humans, but software designed to look for those patterns can potentially recognize that it came from Claude.
The announcement has reignited debate over whether AI watermarking is finally the answer to identifying AI-generated writing or if it even works.
